ClinConnect Summary

This clinical trial is studying the effectiveness of a special type of hip implant called a dual mobility acetabular cup during revision total hip arthroplasty (THA), which is a surgery to fix or replace an old hip joint. Researchers want to see if using this dual mobility design can reduce the chance of the hip dislocating in the year after the surgery, compared to a traditional single bearing design with larger components.

To participate in this trial, individuals must be at least 18 years old and scheduled for a revision hip surgery. This includes patients who are having their previous hip replacements fixed or replaced, or those converting from other types of hip procedures. Those who are not eligible include people under 18, those undergoing their first hip replacement, or patients who refuse to take part. Participants in this trial can expect to receive either the dual mobility implant or a standard one, and their progress will be monitored closely to compare outcomes. This study is important as it may help improve hip surgery results and reduce dislocation rates for patients in the future.

Eligibility criteria

• Inclusion Criteria:
• • Any patient older than 18 years of age scheduled for a revision THA, including revision of both components, conversion of a hip resurfacing to THA, conversion of a hemiarthroplasty to THA, and revision of single components which allow implantation of dual-mobility bearings. In addition, patients undergoing reimplantation of a total hip arthroplasty following a two-stage revision for periprosthetic infection will also be included. Only patients with an acetabular shell diameter capable of accommodating at least a 36mm femoral head will be included.
• Exclusion Criteria:
• • Less than 18 years of age, primary THA,
• • conversion of non-arthroplasty femoral neck fracture fixation to THA,
• • patients unwilling to participate.
• • patients where the surgeon makes the intraoperative decision to use a constrained liner will be excluded.
